The' part or stem portion 21 of each lever is pivoted at 22 within aslot 23 of 'a bracket 24, which bracket is seciired to the plate 25-extending transversely of the machine, and the upper end of each part 20of' the keylevers may be bent, as at 26, and is providedv with a pin 27adapted to move in a slot at 28 at the inner end of the type-bar 29adjacent to.pivot 29. The part 20 of 4each key-lever forms a connectingmeans between the keylever and the type-bar, andthe part 21 of eachlever forms a each lever and by having each lever constructed in themanner shown, the ent-ire key-.lever and connection. with the type-baris made of a single piece and is much better and a more effectivemovement is thereby the said bars will move slowly at first and as thepins approach nearer the pivoting point, the said type-bars will begiven a n1uch.quicker movement, thus saving much time and permitting thebars to be more rapidly operated without suddenly starting and stoppingsaid type-bars during their greatest speed. j

Each key-lever is pivoted at 22 in the blocks .or brackets 24, and theseblocks are arranged in staggered relation and are each adapted to holdfour key-levers. The keylevers, in the form of machine shown, arearranged in four, rows and each typebar may have its head provided withthree characters. As shown the blocks or brackets 24 have the slottedportions 23 somewhat extended to provide proper guiding means' for theinner. en d of the' key-levers 19, and arranged iii an opening 30 is a,spring 31, Figs. 5 and 6, onefor each key-lever, which normally forcesthe outer end of the finger part 18 upwardly to return the same to itsnormal position, the tension of each spring be- 4ing varied by a screw303. These springs maybe arranged in any desired way, and by providingthe blocks or brackets 24 in the manner shown and in a staggeredrelation, the said' levers are properly guided in the lblocks orsupporting' brackets and said brackets may be readily .made and placedin po ition in the machine. L

-Ixgtead of the typestriking against the usu f cylindrical platen,'thetype may engage aat surface,l as 31, formed as a part ,of a plate 31bwhich extends transversely ofthe machine'I and is movable with thecarriage 32, the said carriage having a supple- ,65 mentary frame member32*L and a main. l

ivoting` portion forl frame member 32b to the former of which the plate31h is secured. The plate 31b forms the pl'aten Fig. 2, and may becurved for a greater part of its width except at the .straight part 31,folming 'the printing point, and said plate may be'secured to the part34 of the carriage frame member 32a or otherwise held as desired in aposition so that the paper V'or work .may be readily passed about thesame; though instead of the type striking'directly against a metalvsurface, a

yieldingsurface or strip 35 may be provided and which strip may be soattached/that it may be readily replaced incase of wear. lA

bar 36, Figs. 1 and 2,' extends transverselyof the machine to the rearof the fixed platen 31, and to the bar may be held the Workengagingfingers 37 which may be adjustable along the bar 3G by means of thescrews l 3S. By this 'means the work may be properly guided about theplaten 31"4 so as not to interfere with the type and cause the same tomake two impressions where a plurality of characters are formed onthetype head, as the work immediately on leaving the printing point ismade to bend over the surface'of the curved platen, and `further theVarious type characters are not 'required to be curved to eorrespond tothe curvature of the usual cylinder, forming thepla-ten, as

is the case with .machines of this character. y

A roll .39 corresponding to the usual platen roll may be journaled inthe frame member 321 of the carriage l32, and 'may be provided `withfinger pieces 40 by which the roll may be rotated, the said lingerpieces 40 being secured to the shaft of the roll 39, andto permit theroll and platen frame to move vertically the ends oi the main carriageframe ineniber 32" are slotted where the shaftpasses through saidmember.- At the rear of the roll 39 is a seeondsmaller I'oll .41, whichnormally engages the roll 39, and at the front of said roll 39 is astill smaller roll 42. The shaft 43 of the roll 41 is held in slots 44in the frame member 32 and has peripheral Vgrooves at the ends thereof,and held to the ends of the shaft in Such a way as te` permit the shaftto rotate are the springs 45 which have one end connected to levers 4G.-'l,`hese levers 46, Fig. 7 are pivoted at 4T, and have their innerends, as 4S, `adapted to be engaged by screws 49, so that the tension ofthe springs 45 may be varied and the roll 41 yieldingly held againstthelarger feed roll 39. The roll 42 is similarly held to the roll 39, andhas the ends of its 51 of. the' carriage frame member 32, and

conne'ctedto said shaft are the springs 52V which are connected to thelevers 53, the

latter being pivoted at 54 and normally .forced in one` direction byscrews` to vary the tension of said springs.

To properly support the carriage and the. platen and paperfeed, and tocompensate for wear, we may provide a ball-bearing connection betweenthe carriage andthe ma vertically movable bar '100, and extendingbetween the side members of the carriage frame -member 32b is a bracebar 102.v A-

bearing bar- L03 is 'arranged directly over the bearing bar 100, andsaid bearing bar 108 may move vertically between the 'pms 1 104:`projecting inward from the side members or ends of the carriage framemember 32". .The pins serve to guide the bar 103 in its verticalmovement with the platen, and interposed between the bearing bars 103and 100 are balls or bearing. membersA 105. These bearing members may betwo in l number, and may be connected by a wire 106 to move in unison,and extending upward from the bar '100 may be one or more brackets 107,the upper end of which may be bent at an angle to extend over the 'uppersurface of the bar .103. The bar 101 is fixed to the machine frame whilethe bar 102 is fixed to the carriage, and the Abearing bars 100 and 103are both movable vertically with the platen frame member 32 independentof the carriage frame member 32", though only the bar 103 movestransversely with said carriage frame members.

A second bearing 108 is provided. This 40 "bearing comprises a pluralityof bars or connection 114, Figs. 1, 8 andl 9, and these wires have theirouter ends bent to form aloop for the balls and to space the-latterproperly apart. Held to the wires or connections 114 are the clips 115which are adapted to. fit about the bar 110 to per1nit the balls to movein unison and tobe properly adjusted, and to be movedlengthwise of thecarriage incase the same should be` come displaced Vduring the movementof the carriage or for any other reason. The lower bar 109 has twobrackets- 116 extending upwardly therefrom at or near the ends therevof,and said brackets each have one end formed at an angle and provided witha screw 117 which is adapted to engage the upper surface of the-bar 111so as to force the upper and lower Vbars toward each other tocompensate-for any wear that might occur through the bal1-bearingconnection. The bearing as shown provides an effective means forpermitting the carriage to be shifted along its support, and to hold'the`same substantially rigid and 'free of all lost motion.

500,098, filed June 7, 1909; the keyboard in our application Sr. No.500,694, filed June 7, 1909; the platen in our applicationSr. No.500,695, filed June 7, 1909; the paper feed in our application Sr. N.500,696, filed June 7, 1909; and other features in other' eopendingapplications iled by us.

From the foregoing, it will .be seen that a slmple and efliclentcarriage is provided in which the platen has a shift movement in a frameprovided thereforentirely independent of the rest of the carriage,'andthe said carriage and other mechanism so constructed and arranged thatthe machine is adapted for visible writing; and that simple andefiicient bearings are provided for the carriagewhereby the carriage isproperly sustained and supported in its movement along its support.
